Allrite, are you serious about Craig? Seems to me an A-list film actor wouldn't do TV. Dr. Who will have to abandon its original Timelord mantra if it keeps having to regenerate the Doctor. By my count, Tennant is the 10th actor in the series, including the 1996 TV movie, to play him and I recall the original series stated Timelords could have only 12 incarnations and die for good after that. The renegade Timelord, the Master, was able to cheat and defy that with a convoluted scheme but it's against the Bible of the show for them to do it. Only 2 more actors can now play the Doctor before they must come up with a novel twist on how they can keep him going. Can't wait to see how they write themselves out of that corner.

dont forget that the Doctor now has a daughter who seems to be capable of at least a partial regeneration , so Jenny presumably has 11 or so incarnations up her sleeve if necessary .
